74ALVT16373DL,112

Overview

The 74ALVT16373DL,112 is a 16-bit D-type transparent latch manufactured by Nexperia USA Inc. It features 3-state outputs and supports dual 8-bit configurations. The device operates within supply voltage ranges of 2.3V to 2.7V and 3.0V to 3.6V. It utilizes a 48-TSSOP package with a width of 6.10mm. Propagation delay is specified at 2ns. Output drive capabilities include 8mA/24mA for high states and 32mA/64mA for low states. Operating temperature spans from -40°C to +85°C.

Feature Summary

• Transparent data storage allowing direct input-to-output transmission when enabled
• Three-state output buffers enabling bus line sharing without external resistors
• Partial power-down protection via I_OFF circuitry to prevent backflow current
• Bus-hold inputs to maintain defined logic levels on unused pins

Applications

• High-speed parallel data buffering in communication systems
• Memory address latching in embedded controller architectures
• Data acquisition interface modules requiring isolated storage
• Automotive body control unit signal processing

Procurement Notes

Verify the specific suffix '112' against manufacturer documentation to confirm exact packaging and reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Ensure design compatibility with the specified 48-TSSOP footprint and thermal dissipation limits during operation.

Selection Notes

Select this component for designs requiring high-density 16-bit latching with fast propagation speeds. Verify that the system voltage aligns with the supported 2.3V-2.7V or 3.0V-3.6V ranges. Consider the 48-pin TSSOP package constraints for PCB layout. Evaluate the need for partial power-down features if the application involves standby modes.

Part Context

This part belongs to the 74ALVT series, designed for advanced low-voltage transistor-transistor logic applications. It serves as a critical interface component between high-speed processors and peripheral memory devices. The series emphasizes low power consumption while maintaining high drive capability for transmission lines.

Replacement Considerations

The SN74ALVTH16373DL from Texas Instruments is a confirmed substitute part number.
